Removal & Installation

Disconnect wire harness connector and remove oxygen sensor. If exhaust sensor is difficult to remove, use rust penetrant to avoid possible damage to exhaust threads. If new sensor is not pre-coated with anti-seize, apply anti-seize compound to sensor threads. DO NOT remove anti-seize from sensor. Tighten sensor and attach wire harness connector.
